rent to own shed for Sole Proprietor home business

This is my first year filing as  a Sole Proprietor. I have a rent to own shed I use 100% for my home business. I am trying to figure out where to put this information on my taxes. I have interest I pay every month along with the payment. I'm not sure if I should put the interest in as "mortgage interest" for just the business or do I not claim any payments and somehow claim shed under Assets to be depreciated?
